1. перепробовал Win Server 2008, 2012, 2016
2. нет и в момент появления ошибок порты прослушиваются сервисами Domino
3. IPv6 нет
4. transactions logs не используется
Проблема началась после обновления с 8.5 x86 на 9.0.1 x64 и перехода на WinSrv x64. Зависимости от нагрузки сервера нет, памяти занято 20-30%. Кроме Domino на сервере ничего нет. Каких-то событий, предшествующих ошибке в логах нет. Вот кусочек лога:
